Hi, gang. I updated our experimental hamster FC3 machines via yum to the latest patches and kernel 2.6.9-1.681_FC3. I then did a CVS checkout of the cluster code and did a rebuild of our GFS system against the 2.6.9-1.681_FC3 source tree. When I did the "make" on the device-mapper, there was an issue with the fact that the kernel header for dm-ioctl.h and that in the device-mapper code didn't match, nor was there a patch for it. The compiler pooped saying there you can't "sizeof" an incomplete data type...in this case dm_target_msg. Investigating, I found that the kernel header didn't contain a definition of the dm_target_msg structure (hence the compiler barf) and there were differences in the commands enum as well. I copied the dm-ioctl.h from the CVS device-mapper fileset to the kernel headers and everything went fine. I did not rebuild the kernel after copying the file, but so far it all works. Should it poop out, I'll rebuild the kernel with that new header. Just thought you'd like to know. ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - Overweight: When you step on your dog's tail...and it dies. - ----------------------------------------------------------------------
